Set PDF TrimBox

Set PDF TrimBox

[Henning Hraban Ramm]

Hi Hans,

in May Harald König asked about setting the TrimBox value in PDFs and provided even a patch for lpdf-mis.lua; you promised to look into that, see http://article.gmane.org/gmane.comp.tex.context/91544/

If there’s only one paper size (from \setuppapersize), TrimBox is the same as CropBox.

If there’s a second paper size (like from \setuppapersize[A4][B4]), TrimBox is the first.

At least if there’s "marking=on|color|..." in \setuplayout, please also set BleedBox, even if we can’t influence the bleed value.

Would be nice if there would be an option to let CropBox be the same as TrimBox or BleedBox.

We don’t need ArtBox (in PDF/X it must not differ from TrimBox, if defined).

Could you please implement this? Should be really easy…
I’m tired of fixing the boxes in Acrobat every time.
Thank you very much!

Greetlings, Hraban

The next beta will have this extra 'feature':

\showframe

\setuplayout
   [location=middle,
    width=middle,
    height=middle,
    cropoffset=auto,
    trimoffset=1bp,
    bleedoffset=2bp,
    artoffset=2bp]

\starttext

\definepapersize[TestA][width=100bp,height=200bp]
\definepapersize[TestB][width=150bp,height=250bp]

\setuppapersize[TestA][TestB]

test

\stoptext

The auto option only works with layout=middle (message otherwise) as I'm 
not going to add all kind of extra calculation code to an already bit 
overloaded mechanism deep down. The offset are accumulative (so crop < 
trim < bleed < art). In Haralds case cropoffset=auto should be enough. 
The default crop and trimbox handling is unchanged (as it would 
complicate my own workflows and also breaks compatibility) so one really 
needs to set this when it's needed. The already present 
interactionscreen cropping is unchanged.

Hans

Hi Hans, thank you very much for looking into that!
I wikified the box information plus your example at http://wiki.contextgarden.net/PDF_Boxes

Unfortunately, the order (crop < trim < bleed < art) is not so good, it should be (art < crop < trim < bleed) - as I wrote, in PDF/X, ArtBox must be the same as TrimBox, if defined at all. Would you please fix this?

(I don’t know any use of ArtBox - it was meant for imposition, but software will probably look for page contents itself, since ArtBox is mostly undefined.)

Hm, did you mean, you commented the whole code? I’m updating daily, but Acrobat doesn’t show me any boxes.
Or did maybe my update ignore some files? Which should I check?
